Fall planting confusion
I am a bit confused about fall planting dates (especially tomatoes). I was considering visiting the tomatoman's daughter here in a week or so, but now I think about it I'm not so sure.
OSU's guide says to put out tomato transplants between July 1 and July 15. However temps are too high for fruit set all the way through the end of August. That's a month and a half to two months for the plant to just sit in the heat with no possibility of setting fruit. Why put them out so early? I understand first frost average in this zone is October 16th. From Sept 1st (when we'd likely get fruit set again) to mid-October is only 45 days.
What am I missing here? Logistically, it makes no sense to plant fall tomatoes. Someone please explain to me how this works. Thank you kindly.
P.S. I've selected early DTM varieties and plants that (allegedly) produce in high heat.
